Product Description

1, Overview of QJ deep well pump products It can also be used for pumping water from underground water, underground water pump, underground water pump, underground water pump and so on.

2, Significance of QJ deep well pump model

3, The features of QJ submersible pump are as follows: 1. Submersible multi-stage pump is centrifugal or mixed flow type; water lubricated bearing is used; coupling rigid connection is used for connection with motor. The impeller of the pump is driven by the motor to generate centrifugal force, which increases the liquid energy and carries out water lifting through the diversion function of the pump shell. A check valve body is set at the upper end of the water pump to prevent the working parts from being damaged by the backflow water in the lifting pipe when the electric pump is shut down. There is a drain hole on the valve, which can slowly drain the water in the pipeline to prevent the pipeline from freezing and cracking in winter. (Note: low head submersible pump does not have check valve body) 2. The motor of deep well submersible pump is a closed water filled wet structure. Motor stator winding insulation, nylon sheath multilayer structure of electromagnetic wire. The guide bearing and thrust bearing are made of water lubricated material. The motor is filled with clean water to cool the motor and lubricate the bearing. A pressure regulating membrane is installed at the bottom of the motor to adjust the expansion and contraction pressure difference of water in the body caused by the temperature rise of the motor. The upper shaft of the motor is equipped with a sand control mechanism, which is used to prevent the mud and sand in the water from entering into the body of the deep well submersible pump. 3. Pipeline part: it is used to connect the multi-stage pump, which is installed in the machine well to transport water to the ground. It is mainly composed of short water pipe, water pipe, elbow, splint and other parts of the electric pump installation parts. The short output pipe is the connecting transition part between water pipeline and multi-stage pump. The elbow is installed at the wellhead to change the direction of water flow. The splint is used to lift and fix the output pipeline in the process of chemical pump installation.

Instructions for use 1, Fill the motor with clean water before use, and tighten the water injection and air release bolt. 2, The test run on land shall not exceed one second. 3, Do not use the electric pump. 4, The motor must be fully submerged, but the depth of submergence should not be more than 70 meters. 5, Lead wire and cable joint shall be operated according to regulations (see the figure for details). 6, Order high head submersible pump (high head submersible pump type Atlas) and (high head submersible pump manual).

Conditions of use

The submersible pump can be used continuously under the following conditions:

1. Three phase AC power supply with rated frequency of 50 Hz and rated voltage of 380 ± 5% v. The water level of the submersible pump is less than 70 meters, but the water level of the static water pump shall not exceed 70 meters, The water depth between the lower end of the motor and the bottom of the well is more than 1 m. 3. The water temperature shall not be higher than 20. c. 4. Water quality requirements: (1) sand content in water shall not be greater than 0.01% (weight ratio); (2) The pH value ranged from 6.5 to 8.5 (3) The content of chloride ion is not more than 400 mg / L. 5. It is required that the well should be positive and smooth, and there should be no staggered well pipes

matters needing attention: The cable joint shall be carried out in strict accordance with the attached drawings; 1. Before going down the well, check whether the screws of each part are loose, whether the cable is broken, whether the motor is leaking, and whether the rotation of the motor shaft and water pump shaft is flexible and free of obstruction; 2. Before running into the well, check that the motor resistance should be above 150 m Ω 3. Motor water injection should be carefully prevented from false full; 4. Protection switch and starting equipment shall be equipped according to regulations; 5. When the motor is running for 2500d, a major overhaul should be carried out, and a minor overhaul should be carried out at 1500d; 6. When the electric pump is stopped for storage, the water stored in the motor shall be drained completely; 7. It is strictly forbidden to pretend that you don't understand. Disassembly and repair should be carried out in our factory or fixed repair factory; 8. Frequent "start" and "stop" are prohibited: 9. Ground test motor steering shall be carried out within one second in an instant; 10. When installing the electric pump, be careful to prevent foreign matters from falling into the well; 11. Stop the machine for maintenance in case of the following conditions: (1) The current and voltage exceed the rated value. (2) The flow rate decreased significantly. (3) Water pump intermittent water or sound vibration is large. (4) The protection switch trips frequently. (5) The motor resistance is less than 0.5 megohm.

Fault phenomenon	Possible causes	Exclusion method
The insulation resistance is too low and the winding is burnt out	1. Water inlet joint; 2. Winding damage; 3. Cable rupture; 4. Water shortage in the motor; 5. Phase loss operation; 6. Overload operation for a long time; 7. The motor is buried in the sand.	1. Fix the joint. 2. Wrap or replace the winding. 3. Wrap up the cable. 4. The motor shall be filled with clean water. 5. Check the circuit and equipment to ensure normal operation. 6. Reduce the load so that the motor current does not exceed the value specified on the rating plate. 7. Install the electric pump according to the installation requirements.
The unit vibrates violently or the current is too large, and the pointer of ammeter swings	1. Pump shaft or motor shaft bending; 2. Excessive wear between pump shaft motor and bearing; 3. The thrust bearing is worn or damaged; 4. The fastening nut of thrust disk is damaged; 5. The thrust disc is broken; 6. The motor rotor sweeps the bore; 7. The rotor of impeller or rotor is broken; 8. The connecting bolt is loose; 9. Low lift and large flow pump motor overload; 10. The water inflow of the pump is not enough, and the water is discharged intermittently.	1. Repair or replace pump shaft or motor shaft. 2. Replace the bearing. 3. Replace the thrust bearing. 4. Install the nut or repair the shaft head. 5. Replace the thrust disc. 6. Find out the cause and repair it. 7. Make dynamic balance and replace rotor. 8. Install the bolts. 9. The gate valve is added to control the flow at the operating point. 10. Add gate valve to control water output.
